Utility model content
The purpose of this utility model is in that for above-mentioned defect of the prior art, it is provided that one can resist adverse weather condition, it is to avoid stops working suddenly and causes fuel gas to assemble detonation, the hand-held torch inner core of simple and practical flame-out autonomous resume combustion.
To achieve these goals, the technical solution adopted in the utility model is:
Including combustor, in combustor, it is provided with combustion chamber, ignition electrode and fire testing needle；Described combustion chamber connects gas cylinder by appendix, and appendix connects plug valve and the ignition switch with plug valve mechanical linkage；Described ignition electrode, fire testing needle and ignition switch connect the circuit board controlled for fire defector with resume combustion by wire.
Described circuit board includes switch and the agitator being connected with switch, and the induced voltage outfan of agitator connects Ignition capacitor and booster transformer respectively through rectification circuit, and booster transformer connects ignition electrode.
Current path is formed between described fire testing needle ionizing particle stream and earth terminal in combustion flame.
Described plug valve is connected with the end of appendix by adapter.
Described appendix surrounding is provided with the fixed support for upwards supporting combustor.
Being provided with battery draw-in groove on described fixed support, the battery being arranged in battery draw-in groove connects circuit board by wire.
Described fire testing needle head outwards bends the surface extending to combustion chamber.
It is filled with liquid petroleum gas (liquid propane gas) in described gas cylinder.
Described appendix connects combustion chamber through premix chamber.
Compared with prior art, this utility model has following beneficial effect: arranges fire testing needle and detects flame combustion situation in real time, combustion chamber connects gas cylinder by appendix, appendix connects the ignition switch with plug valve mechanical linkage, open plug valve, fuel gas in gas cylinder enters combustion chamber immediately, and ignition switch closes, and ignition electrode top produces arc ignition fuel gas.Fire testing needle of the present utility model, ignition electrode and ignition switch are connected by circuit board, and when torch stops working suddenly, fire testing needle triggers ignition switch and opens, and ignition electrode opens ignition function immediately, and ignition electrode continuously sends out electric arc, until torch is rekindled.This utility model improves the ability of the anti-adverse weather condition of hand-held torch so that it is using more extensive, the ability of its flame-out autonomous resume combustion has also fundamentally been stopped because torch extinguishes the potential safety hazard causing fuel gas to assemble detonation.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Referring to Fig. 1, this utility model structurally includes combustor 1, is provided with combustion chamber 2, ignition electrode 4 and fire testing needle 3 in combustor 1.The head of fire testing needle 3 outwards bends the surface extending to combustion chamber 2.Combustion chamber 2 connects gas cylinder by appendix 6, and appendix 6 connects combustion chamber 2 through premix chamber 5.Filling liquid propane in gas cylinder, appendix 6 connects plug valve 11 and the ignition switch 12 with plug valve 11 mechanical linkage, and plug valve 11 is connected with the end of appendix 6 by adapter 10.Appendix 6 surrounding is provided with the fixed support 7 for upwards supporting combustor 1.Being provided with battery draw-in groove 8 on fixed support 7, the battery being arranged in battery draw-in groove 8 connects circuit board 9 by wire.Ignition electrode 4, fire testing needle 3, ignition switch 12 is respectively through ignition electrode wire 14, fire testing needle wire 15, and switch wire 13 connects the circuit board 9 controlled for self-inspection.
Referring to 2,3, circuit board 9 of the present utility model includes switch GK, and with the switch agitator that is connected of GK, the induced voltage outfan of agitator connects Ignition capacitor C4 and booster transformer B2, booster transformer B2 connection ignition electrode 4 respectively through rectification circuit.L1, L2, L3, R4 of audion T5 and transformator B1 etc. form agitator, switch on power switch GK, audion T5 just produces vibration, then higher voltage is induced at the L3 end of T1, charge to Ignition capacitor C4 after diode D1 halfwave rectifier, induce higher electric pulse at the L4 end of booster transformer B2 simultaneously and light a fire.When combustion gas is lighted, burned flame can produce the ionizing particle stream with electric conductivity, make to be formed between fire testing needle 3 and earth terminal current path (resistance is about 5-2OM Ω), be now automatically stopped igniting.When after fray-out of flame, open circuit between fire testing needle 3 and earth terminal.Electric pulse carries out ignition operation again automatically, makes combustion gas automatically can be rekindled by lighter again after flame-out.
Operation principle of the present utility model is: open plug valve 11, and the ignition switch 12 of its immediate installation is backed down by machinery, now produces electric arc between ignition electrode 4 top and combustion chamber 2；Open the liquid petroleum gas (liquid propane gas) gas nature vaporized expanding being simultaneously attached in the gas cylinder of plug valve 11 lower end of plug valve 11, and it is connected device 10 successively by plug valve 11, appendix 6, premix chamber 5 enters in combustion chamber 2, now, enter the arc ignition that fuel gas ignited pin 4 top in combustion chamber 2 produces, and in combustor 1 sustained combustion, the fire testing needle 3 being positioned at combustor 1 detects that signal is fed back to circuit board 9 after lighting by torch, and namely the electronic control system on circuit board 9 can close the ignition function of ignition electrode 4.
Torch is in use, it is positioned at fire testing needle 3 continuous firing of combustor, detection flame combustion situation, suddenly (except dying) is stopped working when torch in use runs into uncontrollable factor, misfire signals can be passed to road plate 9 by fire testing needle immediately, electronic control system on circuit board 9, after receiving misfire signals, is opened ignition electrode, is made torch rekindle.
